Description

Technical Field

[0001] This utility model belongs to the field of computer technology, and in particular relates to an automatic power-on / off control system for an Oculink docking station. Background Technology

[0002] Mini PCs have won the attention and favor of many customers due to their lightweight, quiet operation, and high performance. However, due to their compact design, mini PCs cannot accommodate high-performance discrete graphics cards, resulting in relatively weak graphics processing capabilities. Therefore, some users who require high graphics card performance will connect an external expansion dock to their mini PC to improve its graphics card performance. Currently, the most common graphics card expansion docks on the market are Thunderbolt and Oculink. Among them, Oculink expansion docks are recognized by many users for their high bandwidth and low price. However, as an external device, ordinary Oculink expansion docks require users to manually turn the power on or off, which is inconvenient. Utility Model Content

[0003] To solve the above technical problems, this utility model provides an automatic power-on / off control system for Oculink docking stations, the specific solution of which is as follows:

[0004] An automatic power-on / off control system for an Oculink docking station is provided, comprising a mini PC host and a docking station connected by an Oculink cable. The docking station includes an Oculink I / O unit, a circuit detection unit, an electrical switch control module, a power switch key, an ATX power interface module, and a PCIe slot module. The circuit detection unit is electrically connected to the Oculink I / O unit and is used to receive and identify power-on and power-off signals from the mini PC host. The circuit detection unit is electrically connected to the electrical switch control module and is used to transmit execution signals to the switch control module. The electrical switch control module is electrically connected to the power switch key and is used to control the on / off state of the power switch key. The electrical switch control module is electrically connected to the ATX power interface module and is used to control the disconnection and connection of the ATX power interface module with the ATX power supply. The circuit detection unit is electrically connected to the ATX power interface module, and the ATX power interface module is electrically connected to the PCIe slot module to supply power to the PCIe slot module.

[0005] Preferably, after the circuit detection unit detects the power-on signal of the mini PC host, it sends an execution signal to the power switch control module. The power switch control module executes the signal command to simultaneously control the power switch key to disconnect and control the ATX power interface module to power on, so that the ATX power supply starts to supply power.

[0006] Preferably, after the circuit detection unit detects the minipc host shutdown signal, it sends an execution signal to the power switch control module. The power switch control module executes the signal command to control the power switch key to close and turn on, and at the same time controls the ATX power interface module to turn off, thus turning off the ATX power supply.

[0007] Preferably, the power switch key is a dual-purpose switch for both automatic and manual operation.

[0008] Preferably, the ATX power interface module is connected to an external ATX power supply.

[0009] This utility model's docking station automatic power-on / off control system connects the docking station to the OCULLINK interface of the computer host via an OCULLINK cable. When the mini PC host is powered on, the circuit detection unit recognizes the host's power-on and performs two control steps simultaneously: firstly, it disconnects the power switch key, rendering the docking station's power switch key inoperable and cutting off its influence on the docking station; secondly, it controls the ATX power interface module to ensure normal ATX power supply, allowing the OCULLINK docking station to automatically power on following the host. When the computer host is powered off, the circuit detection unit recognizes the host's power failure and performs two control steps simultaneously: firstly, it controls the ATX power interface module to cut off ATX power, allowing the OCULLINK docking station to automatically power off following the host; secondly, it closes the power switch key, allowing the docking station to be started by pressing a physical switch.

[0010] Figure 1 The diagram shown is a schematic diagram of the structural principle of this utility model. Detailed Implementation

[0011] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0012] Please refer to Figure 1An automatic power-on / off control system for an Oculink docking station is disclosed. This system comprises a MiniPC host and a docking station connected via an Oculink cable. The docking station includes an Oculink I / O unit, a circuit detection unit, an electrical switch control module, a power switch key, an ATX power interface module, and a PCIe slot module. The circuit detection unit is electrically connected to the Oculink I / O unit and is used to receive and identify power-on and power-off signals from the MiniPC host. The circuit detection unit is also electrically connected to the electrical switch control module and is used to transmit execution signals to the switch control module. The electrical switch control module is electrically connected to the power switch key and is used to control the on / off state of the power switch key. The electrical switch control module is also electrically connected to the ATX power interface module and is used to control the disconnection and connection of the ATX power interface module to the ATX power supply. The circuit detection unit is electrically connected to the ATX power interface module, and the ATX power interface module is electrically connected to the PCIe slot module to supply power to the PCIe slot module.

[0013] Furthermore, after the circuit detection unit detects the power-on signal of the mini PC host, it sends an execution signal to the power switch control module. The power switch control module executes the signal instruction to simultaneously control the power switch key to disconnect and control the ATX power interface module to power on. The ATX power supply then starts supplying power to the Oculink expansion dock, which powers on and runs along with the mini PC to perform the function of an external graphics card.

[0014] Furthermore, after the circuit detection unit detects the miniPC host shutdown signal, it sends an execution signal to the power switch control module. The power switch control module executes the signal instruction to control the power switch key to close and turn on, and at the same time controls the ATX power interface module to turn off. When the ATX power is turned off, the Oculink expansion dock also turns off along with the miniPC, stopping the external graphics card expansion function.

[0015] Furthermore, the power switch key is a dual-function switch for both automatic and manual operation, retaining the function of manually turning the dock on and off. Due to potential design differences on the computer host side, when the circuit detection unit cannot correctly identify the power on / off information, the user can manually turn the dock on or off, which can increase the compatibility of the Oculink dock.

[0016] Furthermore, the ATX power interface module is connected to an external ATX power supply, which remains electrically connected to the ATX power interface module, and its on / off state is controlled by the electrical switch control module.

[0017] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
